WIRE LOOP.

Application filed April 13,

To all whom it may concern:

Be it known that I, O'rro A. MIor-InLIs, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in lVire Loops, of which the following is a specification.

This invention relates to wire loops for connecting springs and. wires and to a disposition of the end. portions thereof whereby the loop may be readily snapped over a wire, the jaws of the loop being so arranged with. respect to the wire that it readily enters between the same.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings Fig. 1 is a View of a pair of springs united by a loop that embodies features of the invention; Fig. 2 is a View of a loop slightly spread by the insertion of a wire, the latter being omitted for a clear View; Fig. 3 is a View of a loop showing the position the jaws or arms thereof assume when forced. against the wire; Fig. l is a View showing the position assumed as the wire enters further between limbs of the loop; Fig. 5 and 6 are views in detail of the loop without the wire.

As herein shown, a loop 1 is formed of a piece of spring wire, bent between its ends to form parallel arms 2 and 3, the end. portions of which are disposed so that a return limb l of the arm 2 overlies the arm 3 while a corresponding member 5 of the arm 3 underlies a portion of the arm 2; the bond 7 which unites the parts 3 and extending sufficiently beyond the bend 6 which unites the parts 2 and 4 so that an entrance angle is formed by the overlap. In use, a wire 8 when pressed. into this angle formed by the overlappin g bends 6 and 7, forces the arms apart and is readily slipped along as indicated in Figs. 3 and 4: until it clears the shorter limbs. This complete entrance into the loop permits the latter to be turned as indicated in Fig. l for loosely articulating two inserted wires 9 and 10.

A feature of the invention is the overlap ping of the loop ends to form an entrance angle into which an applied wire may be read 1921. Serial No. 451,143.

ily placed, thus permitting the loop to be forced home over the wire without the necessity of. first spreading or opening the loop, either by pliers or by the fingers of the operator. This greatly increases the effici-enoy of the loop and ease of operation, a matter which is of great moment where large numbers are used, as in spring seat constructions, and when once applied, the loop is self-locking against any accidental. disengagement.

Another feature is the resistance afforded to opening of the loop when the two wires which the loop secures tend to move apart. if the inner bend commences to straighten out, the strain comes on the second loop and the latter of course has to straighten out in reverse direction to the first loop. Conseouently there is a double resistance to end \vise pull on the loop and the added strength caused by the opposing, straightening motions of the free arms.

lilbviously changes in the detail of construction may be made without departing from the spirit of the invention, and l do not care to limit myself to any particular form or arrangement of parts.

i hat I claim is:

1. The combination in a spring structure comprising a plurality of coiled springs and ties therefor each consisting of a wire loop the arms of which terminate in oppositely disposed hooks disposed in superimposed relation with the bight of one hook projectslightly beyond the other facilitating nent of the loops with adjacent .1 rings, one coil normally lyiu in the closed end of the loop and the other within both of said hooks.

2. in a spi structiu'e, the combination of a plurality of coiled springs and tie loops therefmj having arms terminating in books disposed in opposite v facing superimposed relation with the big it of one hook project'- iug beyond the bight of the other, facilitating the engagement of the loops with the coils of the sprii he bills of the hooks being relatively short. further facilitating s1 ich engagement.

in testimony whereof I affix my signature.

OTTO MIGHELIS.
